Answer:
Step-by-step explanation:
<u>Given </u>
- f(x) = x + 4 and
- g(x) = x + 7
<u>Find (g - f)(x):</u>
- (g – f)(x) =
- g(x) - f(x) =
- x + 7 - x - 4 =
- 3
Correct choice is A
Answer:
10m
Step-by-step explanation:
<u>Perimeter</u> means adding up all of the sides of a shape.
One property of a square is that <u>all lengths of a square are the same</u>.
We also know squares have <u>4 sides</u>.
<u />
Lets set up an expression to solve the length for each side with variable S representing the length of a side:
4 * S = 40
Divide each side by 4:
S = 10
Therefore, each side of the square has a length 10m

Answer:
The price Mr. Randall paid = 4 * (20-5)
Step-by-step explanation:
Answer:
y=0x+2 meaning the slope is equal to 0
Step-by-step explanation:
If you think about this question you'll see that our two points have the same y coordinate
This means that the slope is equal to 0
so we have
y=0x+b
If we plug in -3 for x and set the equation equal to 2 we can find b
0+b=2
b=2
so we have
0x+b=y
Hope this helps!
